Many misinterpreted @VitalikButerin's retweet of ENS's Layer2 data parsing solution as explicit endorsement for ENS's grand narrative. However, a deeper analysis reveals a strategic move to tighten Ethereum's control over Layer2's Data Availability (DA). Here's why:
The Core Value of ENS Domain Services
ENS domains simplify blockchain interactions by mapping complex wallet addresses to human-readable names. This service addresses a critical pain point: the difficulty of remembering and identifying lengthy EOA addresses.

Why Layer2 Integration Matters
- Mass Adoption Potential: ENS's true value lies in serving web3's future mainstream users.
- Scalability Synergy: As Layer2 solutions become Ethereum's primary scaling pathway, ENS must expand beyond the mainnet to remain relevant.
ENS's Layer2 Data Parsing Solution: Technical Breakdown
ENS proposes a decentralized framework for cross-Layer2 domain resolution:
- Interoperability Bridge: A "Layer Bridge" enables Layer2 platforms to securely retrieve and validate Ethereum mainnet domain data off-chain.
Enhanced Protocols:
- EIP-3668: Ensures proper mainnet verification of Layer2 domain usage
- EIP-5599: Decentralizes resolution tasks by allowing Rollup contracts to process requests
Key Implication
This architecture mandates using Ethereum's native DA capabilities, effectively excluding Layer2 platforms that:
- Use OP Stack shortcuts
- Rely on third-party DA providers like Celestia
Vitalik's Strategic Play
Post-Dencun upgrade, Ethereum faces:
- Uncontrolled Layer2 Proliferation: Modular stacks blur traditional DA boundaries
- DA Sovereignty Risks: Without validator control, Ethereum risks becoming merely a "bulletin board" for Layer2s
Vitalik's moves (Plasma+ZK advocacy, ENS promotion) constitute a concerted effort to:
- Maintain Ethereum's DA orthodoxy
- Anchor Layer2 development to Ethereum's security model
Why ENS Chosen as Standard-Bearer?
- Proven Track Record: Ethereum's most successful non-financial application
- User Experience Focus: Aligns with Layer2's mass adoption goals
- Strategic Leverage: Natural tool for enforcing interoperability standards
FAQ Section
Q: Why is DA control so crucial for Ethereum?
A: DA represents the foundational layer where validators ensure transaction integrity. Losing DA control weakens Ethereum's security proposition.
Q: How does ENS benefit from Layer2 integration?
A: It expands addressable market by serving users across all scaling solutions while maintaining decentralization.
Q: Will this affect existing Layer2 platforms?
A: Platforms using alternative DA solutions will need to adapt to support ENS functionality.

Conclusion
Vitalik's ENS promotion is a masterstroke that:
- Establishes cross-Layer2 operability standards
- Strengthens Ethereum's DA governance
- Positions ENS as critical infrastructure for web3's next growth phase
This strategic interplay between protocol politics and technical innovation underscores crypto's unique development paradigm.
